Numerical Modeling of the Fluid Flow in Continuous Casting Tundish with Different Control Devices
Abstract and Applied Analysis, 2013 Numerical simulations were conducted to study the melt flow under the influence of control devices in a T-type two-strand bloom caster tundish via the open source Computational Fluid Dynamics software OpenFOAM.

Viscosity, Density, Surface Tension, and Crystallization Behavior of Commercial Mold Fluxes
steel research international, Volume 96, Issue 5, May 2025.This study explores the properties and behaviors of two mold fluxes used in steel casting. Key findings show that viscosity and density change nonlinearly with temperature. Increased basicity lowers viscosity and raises break temperature, while phase formation time shortens. Time–temperature transformation and continuous cooling transformation diagrams

Mathematical simulation for effects of flow control devices in two-strand slab tundish
Metalurgija, 2017 Fluid flows in a two-strand tundish for slab continuous casting were performed with mathematical simulation methods. The molten steel flow velocity fields in the tundish with a turbulence inhibitor, dam, and weir were numerically calculated.

Journal of the American Ceramic Society, Volume 108, Issue 5, May 2025.Abstract Recently, gahnite (ZnAl2O4) is gaining attraction as a potential refractory ceramic because of the similarity of its structure and properties with those of magnesium aluminate (MgAl2O4) spinel refractories. Formation of MgO and hibonite solid solution (CaMgxAl12−xO19−0.5x; 0 ≤ x ≤ 0.18), CAM‐I (Ca2Mg2−3xAl28+2xO46 (0 ≤ x ≤ 0.3), and CAM‐II ...

Effect of melt conditioning on heat treatment and mechanical properties of AZ31 alloy strips produced by twin roll casting [PDF]
, 2014 In the present investigation, magnesium strips were produced by twin roll casting (TRC) and melt conditioned twin roll casting (MC-TRC) processes. Detailed optical microscopy studies were carried out on as-cast and homogenized TRC and MC-TRC strips.

Materialwissenschaft und Werkstofftechnik, Volume 56, Issue 4, Page 601-611, April 2025.Hot tensile testing of low carbon microalloyed steel at 650 °C–1100 °C and strain rates of 10−2 s−1 and 10−3 s−1 revealed a ductility minimum at 700 °C–850 °C. Thick ferrite films at <700 °C led to ductile fracture, while thinner films in the 700 °C–850 °C range caused brittle intergranular fracture.
